Jubilee 6:24 And Noah ordained them for himself as feasts for the generations for ever, so that they have become thereby a memorial unto him. 25 And on the new moon of the first month he was bidden to make for himself an ark, and on that (day) the earth became dry and he opened (the ark) and saw the earth. 26 And on the new moon of the fourth month the mouths of the depths of the abyss beneath were closed. And on the new moon of the seventh month all the mouths of the abysses of the earth were opened, and the waters began to descend into them. 27 And on the new moon of the tenth month the tops of the mountains were seen, and Noah was glad. 28 And on this account he ordained them for himself as feasts for a memorial for ever, and thus are they ordained. 29 And they placed them on the heavenly tablets, each had thirteen weeks; from one to another (passed) their memorial, from the first to the second, and from the second to the third, and from the third to the fourth. 30 And all the days of the commandment will be two and fifty weeks of days, and (these will make) the entire year complete. Thus it is engraven and ordained on the heavenly tablets. 31 And there is no neglecting (this commandment) for a single year or from year to year. 32 And command thou the children of Israel that they observe the years according to this reckoning- three hundred and sixty-four days, and (these) will constitute a complete year, and they will not disturb its time from its days and from its feasts; for everything will fall out in them according to their testimony, and they will not leave out any day nor disturb any feasts. 33 But if they do neglect and do not observe them according to His commandment, then they will disturb all their seasons and the years will be dislodged from this (order), [and they will disturb the seasons and the years will be dislodged] and they will neglect their ordinances. 34 And all the children of Israel will forget and will not find the path of the years, and will forget the new moons, and seasons, and sabbaths and they will go wrong as to all the order of the years. 35 For I know and from henceforth will I declare it unto thee, and it is not of my own devising; for the book (lies) written before me, and on the heavenly tablets the division of days is ordained, lest they forget the feasts of the covenant and walk according to the feasts of the Gentiles after their error and after their ignorance. 36 For there will be those who will assuredly make observations of the moon -how (it) disturbs the seasons and comes in from year to year ten days too soon. 37 For this reason the years will come upon them when they will disturb (the order), and make an abominable (day) the day of testimony, and an unclean day a feast day, and they will confound all the days, the holy with the unclean, and the unclean day with the holy; for they will go wrong as to the months and sabbaths and feasts and jubilees. 38 For this reason I command and testify to thee that thou mayst testify to them; for after thy death thy children will disturb (them), so that they will not make the year three hundred and sixty-four days only, and for this reason they will go wrong as to the new moons and seasons and sabbaths and festivals, and they will eat all kinds of blood with all kinds of flesh.
